restricts their widespread application. Considering the ready availability and diversity of cyclicamines, we report a visible-light photocatalytic Barbier-type reaction of aziridines and azetidines with nonactivated aldehydes. A series of important γ- and δ-amino alcohols were synthesized in the presence of amines as electron donors. Moreover, this transition-metal-free protocol displays mild reaction
A photocatalyticcarboxylation of C−N bonds in cyclic amines with CO2 is realized by consecutive photo-induced electron transfer (ConPET). This mild and transition-metal-free protocol provides a general and practical route to valuable β-, γ-, δ- and ϵ-amino acids.
